This is a rare leaf from the remains of a Koran, on paper, India, Sultanate, originating in the state of Bihar, circa AD 1425 (330 x 250 mm.). Text is from the end of juz 15 and juz 16-30. There are eleven lines of large bihari script in black ink; the word Allah picked out in red or gold through, first 'ayah' of each juz selected in gold, single verse divisions marked with illuminated gold florets, sura headings written in white on illuminated panels with palmetts extending into the margins, inner and outer margins ruled in red and blue, large finely illuminated marginal devices marking sajda instructions, juz, quarter and half and three-quarter juz, text words in black. Verso: leven lines of large bihari script in black ink. The condition is unusually good condition, damp staining being confined largely to one corner, hardly effecting the text. We consider this 600-year-old leaf to be under fine condition [F-] and a very fine and imposing collectable leaf.
